The utility model discloses a fastener driver, and particularly relates to an electric nailing gun. The launching mechanism and the jacking mechanism are designed to be guided by two groups of parallel guide structures, so that the force transmission between the launching mechanism and the jacking mechanism can be improved, and the vibration of the nailing gun is reduced. And the launching mechanism reciprocates between the first energy storage position and the second striking position through the interaction of the biasing mechanism and the jacking device assembly, so that the fixing piece in the nail box is driven into an object needing to be fixed. The jacking device component transmits the torsion of the output mechanism to the launching mechanism through cooperation between the protruding shaft and the protruding part. The protruding shaft is designed to be cylindrical, and the protruding part is designed to be convex arc-shaped, so that contact between the protruding shaft and the protruding part is always arc-cylindrical contact, friction force between the protruding shaft and the protruding part can be reduced, and transmission efficiency is improved.

The utility model relates to a reversible counterattack hammer crusher hammerhead dismantling device, which comprises a striking device and a guide pipe positioning device, the striking device comprises a rammer, a group of hanging rings are arranged at the top of the rammer, steel wire ropes are connected to the hanging rings on the left side and the right side of the top of the rammer, the other ends of the steel wire ropes are connected to a pair of hanging lugs, and the guide pipe positioning device is arranged on the guide pipe positioning device. Safety ropes are connected to a pair of lifting rings in the center of the top of the rammer, the other ends of the safety ropes are connected to a pair of lifting lugs, and the lifting lugs are assembled on one side of the bottom of the bearing steel beam; according to the device, stable dismounting force can be effectively and fixedly provided, potential injury risks are reduced, staff safety is guaranteed, larger force and more stable supporting can be provided, the number of operators is reduced, and the dismounting process is more efficient and rapid.

This utility model discloses a soil dilution device for soil testing. Relating to the field of soil testing technology, the device includes a housing. A pulverizing component is located at the top of the housing, and a filtering mechanism is located below the pulverizing component. One side of the filtering mechanism is fixedly connected to the interior of the housing, and the other side of the filtering mechanism passes through the housing. A stirring mechanism is located at the bottom of the housing, and an anti-sedimentation component is located at its lower end. A collection component is located in the middle of one side of the housing. The pulverizing component allows for multiple pulverizations of the soil, resulting in more thorough pulverization and greater impact force, breaking up clumps of soil and ensuring a sufficient quantity of soil for testing. The filtering mechanism allows the filter plate to shake and screen the soil, blocking large particles that have not been pulverized, improving the soil's fineness, and breaking up clumps of soil to ensure a sufficient quantity of soil for testing.
